Prior to Mr. Harvey’s appointment, and pursuant to CMS Energy’s and Consumers Energy’s Bylaws, the Boards increased their authorized membership from ten members to eleven members.

Mr. Harvey has no prior relationship with CMS Energy or Consumers Energy and there are no arrangements or understandings between Mr. Harvey and CMS Energy or Consumers Energy pursuant to which Mr. Harvey was elected as a director. He has been appointed to serve on the Compensation and Human Resources and the Governance and Public Responsibility Committees of the Boards.

Mr. Harvey entered into Director Indemnification Agreements with CMS Energy and Consumers Energy, effective August 1, 2012. In connection with his election to the CMS Energy Board, Mr. Harvey will receive a restricted stock grant, in a pro-rata amount of the annual restricted stock grant provided to non-employee directors, effective on August 1, 2012, and such restricted shares will vest 100% three years from the original grant date.
